Granted: 1996-04-02
Abstract: An  optical  head  comprising  a  diffracting  element having two tracking diffracting regions  separated by a division line extending in a direction corresponding to a track direction of a recording medium, and one focusing diffracting region separated from the tracking diffracting regions  by  a  division  line  extending  in  a  direction corresponding  to  a  radial  direction  of  the  recording medium.

Title: System and method for optical recognition of bar-coded characters
Inventor: HIGGINS RAYMOND L
IPC: G06V30/224
Filed: 1991-08-26
Granted: 1998-06-30
Abstract: A system and method are disclosed for optical scanning and recognition of bar-coded characters (e.g., CMC7 type characters having a pattern of bars and intervals) recorded on documents such as bank drafts and checks.  The system comprises an optical scanner, a microprocessor, a read-only-memory (ROM), a random-access-memory (RAM, with a stored program) for storing data and a plurality of pre-determined character-identifying binary codes.  The scanner optically scans each document and produces a plurality of grey-scale pixel values corresponding to the bars and intervals of the characters.  The grey-scale pixel values are then stored in the RAM under control of the microprocessor.  The microprocessor processes the stored pixel values, and effectively locates, and segments each character on the document by taking one or more slices (segments) of each character.  Each segment includes a plurality of grey-scale pixel values representing a horizontal slice of a character. The microprocessor than converts the segment of pixel values to a binary code, and compares the binary code to the predetermined binary codes for obtaining a match, identifying the character.

Title: Digital radio receiver having amplitude limiter and logarithmic detector
Inventor: ICHIHARA MASAKI
IPC: H04L25/03
Filed: 1991-10-24
Granted: 1995-09-05
Abstract: In a digital radio receiver, an amplitude limiter circuit is included for producing a constant-amplitude IF signal from a received digitally-modulated IF signal.  An orthogonal detector orthogonally mixes the constant-amplitude signal with a reference carrier and produces an in-phase baseband signal and a quadrature-phase baseband signal.  The baseband signals are converted to first and second digital signals and supplied to respective multipliers.   A logarithmic detector circuit is coupled to the amplitude  limiter  for generating a  signal representative of the amplitude of the received IF signal.  The logarithmic scale of the amplitude signal is converted to linear scale by a logarithmic-to-linear converter circuit and supplied to the multipliers in which it is multiplied with the digital baseband signals.  The outputs of the multipliers are coupled to an equalizer for eliminating bit errors.  The outputs of the equalizer are then directed to the demodulator for recovering the modulating signal.

Title: Facility and method for d channel packet switching
Inventor: SIEGMUND GERD
IPC: H04M11/06
Filed: 1992-02-26
Granted: 1996-05-28
Abstract: For packet-data switching in the ISDN D channel through a digital exchange, the need for a costly frame handler for processing OSI Layer 2 and 3 functions is to be eliminated.            To do this, in response to destination information in the SET UP message, an OSI Layer 3 control unit (SE3) establishes a connection between the two OSI Layer 2 control units (SE1, SE2) of the exchange (VST), to which the data terminals (DEE1, DEE2) are connectable. Direct packet-data transfer can then take place between the OSI Layer 2 control units without further partici-pation of the Layer 3 control unit.
